Patent GB-2243540-A (GB)
Title: Improvements in or relating to seats for mounting on a vehicle floor
Inventor: DEMOPOULUS ANDREAS
IPC: B64D25/04
Filed: 1990-05-03
Abstract: With reference to (Fig. 1), an aircraft passenger seat (1) is mounted on a floor (2) of an aircraft and comprises a body support frame (3), and a pair of rear legs (4), and feet (6, 7) for attaching the frame (3) to the floor (2) so as to be pivotable about a substantially horizontal axis (8) towards and away from the floor (2). The seat (1) also comprises restraint means in the form of a telescopic device (9) for preventing the pivotable movement unless overridden by impact loadings applied to the seat of a predetermined magnitude. The device (9), which serves as a normally solid strut, is disposed between the support frame (3) and front blocks (27), and is secured thereto by pivotal connections (28, 29). Should an aircraft incorporating the seat (1) make a forced landing whereby the impact load applied to the seat in the direction (95) is up to, say, 9.0 g, the seat, with its occupant, will wish to rotate about axis (8) relative to the floor (2) and in the direction of arrow (96). However, frictional forces in the device (9), imposed by clamping rings (56, 57), resist such pivoting. Should an impact load applied to the seat (1) be, say, 12.0 g in magnitude, the device (9) is overridden by the excess load, thus causing the seat to pivot. This rotational or pivoting movement, indicated by arrow (96), causes the tubular member (40) (Fig. 2) of the device (9) to be forced downwardly, into the tubular member (41), so as to contract the device. As the member (40) is forced into the member (41), the rings (56, 57) apply a substantially uniform frictional gripping force on it which absorbs the excess energy, i.e. the 3.0 g difference between 9.0 g and 12.0 g imposed on the seat (1), as the centre of gravity of the seat and occupant is displaced forwardly. The device (9) is provided with means operable to apply a seat-restoring movement. The device (9) may be replaced by a rotary form of restraint means.

Title: Oxygen-rich gas breathing system for passenger carrying aircraft
Inventor: HARRAL MICHAEL WILLIAM
IPC: B64D13/00
Filed: 1991-02-06
Abstract: A system and apparatus are disclosed for providing oxygen-rich gas for breathing by aircrew and passengers of commercial passenger aircraft. Oxygen-rich gas output by molecular sieve concentrator apparatus 11 is delivered by way of a compressor 17 and a priority valve 24 to a flight crew gas storage cylinder 22 and passenger gas storage cylinders 23. An electronic control unit (ECU) 38 controls cycling of the concentrator apparatus 11 in obtainment of gas enriched with oxygen to at least 90%. The ECU is connected for receiving signals from a monitor 35 which senses the content of oxygen in gas delivered by the concentrator apparatus. The EGU receives signals from pressure sensors 42 and 43 in the cylinders 22 and 23 to initiate start up of the system when the content of these cylinders is sensed to have fallen below a predetermined value. The ECU is connected to switch the priority valve for preferential charging of the crew cylinder when both sets of cylinders require charging. The ECU is further connected for opening a vent 46 whereby on start-up of the system, gas delivered by the concentrator apparatus is vented to ambient until the oxygen concentration is sensed to be 90% or more. The system reduces the requirement for ground servicing and weight of oxygen gas storage cylinders carried by present day passenger carrying aircraft. Also, it enables the number of cylinders to be kept at a minimum in meeting the requirements for emergency oxygen on new air routes which are now being developed. <IMAGE>

Abstract: A circuit for generating a plurality of timing signals includes a plurality of cascade-connected delay cells 10-1 to 10-N. each having an input coupled to an output of another, and a plurality of latches (70-1 to 70-X). Set inputs of various latches are coupled to outputs of various delay cells to determine times of occurrence of leading edges of various timing pulses. Reset inputs of the various latches are coupled to outputs of various delay cells to determine times of occurrence of trailing edges of various timing pulses. The circuit includes a phase detector 21 having a first input coupled to receive a clock signal and a second input coupled to an output of one the delay cells (e.g. 10-N) to receive a signal indicative of propagation of a logic state through a first group of the delay cells, to produce an adjustment signal indicative of whether the phase of the indicator signal is ahead of or behind the phase of the clock signal. Each of the delay cells increases or decreases propagation time through that delay cell in response to the adjustment signal, so as to cause a time required for the logic state to propagate through all of the delay cells (e.g. up to 10-N) to be equal to a period of the clock signal. <IMAGE>
